Fundamental theorem of line integral for Lipschitz continuous function

87 Views Asked by At

Suppose that $f : \mathbb{R}^n \to \mathbb{R}$ is Lipschitz continuous, can we conclude that $$ \int_{[0,1]} (y-x)^T \nabla f(\mu y + (1-\mu )x) \text{d}\mu = f(y) - f(x) $$ where $\int$ stands for Lebesgue integral?
